Chapter 2: Maintenance and Fault Finding
2.1 Maintenance
Servicing and safety
???Raymarine equipment should be serviced only by authorised Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no
???Some products generate high voltages, so never handle the cables/ connectors when power is being supplied to the equipment.
???When powered up, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse affect on operation. In order to minimise these effects and enable you to get the best possible performance from your Raymarine equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).
???Always report any
???In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.
???Always switch off the power to Raymarine equipment before working on it.
When requesting service, please quote equipment Type, Model Number, Serial Number and, if possible, Software Release Issue. The Software Release Issue can be ascertained by means of the Intermediate Calibration facility, see Chapter 4, Calibration.
Instrument
Certain atmospheric conditions may cause a small amount of condensation to form on the instrument window. This will not harm the instrument and will clear after the instrument has been switched on for a short period.
Periodically clean your ST40 instrument with a soft damp cloth. Do
NOT use chemical or abrasive materials to clean the instrument.
Transducer
Refer to the Installation and Maintenance instructions supplied with the transducer.
Cabling
Examine all cables for chafing or other damage to the outer shield and, where necessary, replace and
2.2 Fault finding
Preliminary procedures
If you appear to have a problem, first check the security of the connections at the rear of the instrument and reconnect any that are loose.
Changes in the electronic environment may adversely affect the operation of your ST40 equipment. Typical examples of such changes are:
???Electrical equipment has recently been installed or moved aboard your vessel.
???You are in the vicinity of another vessel or shore station emitting radio signals.

Chapter 3: Installation
This chapter describes how to install the ST40 Speed instrument, and associated speed transducer. The transducer is fitted in the hull of the vessel and is connected to the rear of the instrument.
3.1 Planning your installation
Determine the best positions for both transducer and instrument, such that the EMC installation guidelines and the Site requirements (below) are satisfied.
EMC installation guidelines
All Raymarine equipment and accessories are designed to the best industry standards for use in the leisure marine environment.
Their design and manufacture conform to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC performance, but it is recognised that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever
possible:
???All Raymarine equipment and cables connected to it are:
???At least 1 m (3 feet) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 2 m (7 ft).
???More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degreesabove and below the radiating element.
???The equipment is supplied from a different battery from that used for engine start. Voltage drops below 10 V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode.
???Raymarine specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation manual.
???If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position.
Suppression Ferrites
The following illustration shows typical cable suppression ferrites fitted to Raymarine equipment. Always use the ferrites supplied by Raymarine.
Connections to Other Equipment
If your Raymarine equipment is going to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be fitted to the cable close to the Raymarine unit.
Tools required
The tools required for fitting the standard ST40 instrument system are shown in the following illustration.
Note: If you intend fitting a nonstandard transducer, extra tools may be required
Site requirements
Transducer
The transducer types required for the various hull types are as follows:
Other transducer types are also available for specific requirements. For further details, contact your local Raymarine dealer.
75 mm (2.94 in) diameter
100 mm (3.95 in)
75 mm (2.94 in) diameter
The transducer should:
???Be ahead of the propellers (by a minimum of 10% of the water line length ).
???Be at least 150 mm (6 in) away from the keel (ideally ahead of the keel if a sailing yacht).
???Be as near as possible to the centre line of the vessel.
???Be clear of other
???Have sufficient clearance inside the hull to fit the nut.
???Have 100 mm (4 in) of headroom to allow for withdrawal.
The transducer should be sited within the clear water flow areas indicated by the shaded areas in the following diagram.
Sailing vessel
Planing power vessel
Displacement power vessel
CAUTION:
The presence of moisture at the rear of the instrument could cause damage either by entering the instrument through the breathing hole or by coming into contact with the electrical connectors.
Each instrument must be positioned where:
???It is easily read by the helmsman or navigator
???It is protected against physical damage
???It is at least 230 mm (9 in) from a compass
???There is reasonable rear access for installation and servicing
???The rear of the instrument is protected from water.
3.2Procedures
Adapt these procedures as appropriate, to suit your individual requirement.
CAUTION:
Where it is necessary to cut holes (e.g. for cable routing and instrument mounting), ensure that these will not cause a hazard by weakening critical parts of the vessel???s structure. If in doubt, seek advice from a reputable boat builder.
Fitting transducer
Instructions for installing and maintaining the speed transducer are packed with it. Before attempting to install the transducer, read these instructions and the Site requirements for transducers described in this Chapter.
Running transducer cable
Each transducer has a 9 m (30 ft) cable fitted with spade terminals for connection to the ST40 Speed instrument. Observing the following guidelines, run the cable to the instrument:
???If the cable has to be fed through the deck, always use a good quality deck gland.
???Where cables are fed through holes, always use grommets to prevent chafing.
???Secure long cable runs so they do not present a hazard.
???Wherever possible, route the cable away from fluorescent lights, engines, radio transmitting equipment, as these may cause interference.
Connections to the instrument
You can connect your instrument:
???Directly to the speed transducer as a
???As part of a SeaTalk system either as a repeater or, with a transducer also connected as a system master. To connect to SeaTalk, you will need an additional SeaTalk Interconnection Kit, (Part No. E25028). When connected in this manner, power can be provided from the SeaTalk bus (e.g. from the autopilot).
You can also connect the instrument to both the speed transducer and SeaTalk. When thus connected, the instrument will be the master speed instrument for the SeaTalk system.
If it is necessary to fit spade connectors to the transducer cable, do so as shown in the following illustration. Prepare the cable, as at (a), and fit the spade connectors, as at (b). When fitting each spade connector, ensure that wire strands do not extend beyond the rear of the spade connector insulation.

Desktop Mounting Bracket
An optional Desktop Mounting Bracket (Part No. E25024) enables you to mount your ST40 instrument in locations where other forms of mounting are impractical.
To bracket mount your ST40 instrument, do so in accordance with the Instruction Sheet, which is included with the Desktop Mounting Bracket.
3.3 Calibration requirement
Once installation is complete and before you use your instrument, carry out the calibration procedures detailed in Chapter 4, Calibration.
Chapter 4: Calibration
4.1 Introduction
The procedures in this Chapter must be carried out before the equipment is used operationally, to optimise the performance of the instrument with the vessel.
Calibration information is presented in flow chart form. The flow charts show the various calibration screens and key presses necessary to carry out calibration. All key presses are momentary unless otherwise stated.
EMC conformance
Always check the installation before going to sea to make sure that it is not affected by radio transmissions, engine starting etc.
4.2 User calibration
User calibration enables you to:
???Set the required units for speed readings. Either KTS (knots), MPH (miles per hour) or KPH (kilometres per hour).
???Set the required distance units. Either NM (nautical miles), SM (statute miles) or KM (kilometres).
???Select water temperature units. Either ??C or ??F, as required.
???Set the speed display response. Use higher response values when boating in conditions requiring rapid updates of the current speed (e.g. competition sailing or on power boats). Use slower response values when you require an average speed over a longer period of time (e.g. when cruising, especially in heavy seas).
???Set the correct speed reading, either by using a Cal factor screen to adjust the calibration factor, or by applying Speed Over Ground (SOG) as the current speed. Your vessel must be moving at 0.5 KTS or more and be receiving SeaTalk SOG data, to enable SOG to be applied as the current speed. This should be done only in conditions of zero tide and current.
To carry out User calibration, power up the instrument then follow the procedure in the User calibration flow diagram.
